The purpose of the branch is to increase the velocity of water and may be defined as “A Metal fittings between hose and the nozzle converting pressure energy to provide the nozzle with a solid jet – of water for fire fighting.”…
Pull Cord Switch is an emergency switch to stop the conveyor instantly in any dangerous condition or when an accident occurs. Since the traction cable switch is designed in such a way that it must be installed on the side of the…
What are coal feeders? Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system…
Safety instrumented system (SIS) is a system designed to monitor dangerous conditions in a plant (operation unit) and take action in the event of a dangerous condition or a condition where if no action is taken it will cause danger. This system…
Pitot tube is a device used to measure the fluid flow measurement invented by Henri Pitot, a French engineer in 18th century. It is widely to measure the airspeed of aircrafts, speedboat speed and for fluid flow measurement in industrial application. Pitot tube…
What is Direct Acting ? Direct acting means that valves uses a power supply to open and close. Power is transformed into magnetic force,in a plunger type valve,forces a plunger to move and open or close the valve seats. Other direct…
Thermocouple Gauge Thermocouple gauge is a device used to measure low vacuum.Working of a Thermocouple GaugeIn Thermocouple Gauge a filament is heated by passing constant current through it.When gas molecule interact with filament heat is carried away.Therefor the temperature is directly depended on…
Pirani GaugePirani gauge is a device used to measure low vacuum in a pressure range from 0.5 Torr to 10−4 Torr. Working Principle and Construction of Pirani gauge Pirani gauge consist of two tungsten filaments,a power source and a volt meter or ammeter.One of the filaments is…
What is a Load Cell?Load cell is a device that converts force in to an electrical signal.A load sensor is a sensor or a transducer that converts a load or force acting on it into an electronic signal.This electronic signal can be…
How Differential Flow Meter Works? The differential flow meter is the most common device for measuring fluid flow through pipes. Flow rate and pressure differential of fluids such as gases,vapors and liquids are explored using the orifice plate flow meter. The differential…
